Police are still looking for a man who robbed the Sovereign Bank at 211 North Main St. with a note but no weapon on Monday.
Police received a call reporting the robbery just after 2:30 p.m., June 14.
The alleged robber, a white male, roughly 5 feet, 6 inches tall, and wearing a green top, fled north on Route 28 after receiving an undetermined amount of cash. He was driving a grey S10 Chevy Blazer with a temporary New Hampshire license plate, said police Lt. Commander James Hashem.
The suspect had not been caught by late Wednesday morning, said Lt. Harry Collins. Hashem said the FBI had been notified of the robbery.
The alleged robber entered the bank alone, wearing a hat and sunglasses as he passed the note to a teller. "A number of witnesses" were in the bank at the time, said Hashem.
"It was very low-key, not a takeover style robbery," said Hashem.
No one was injured in the incident.
Bank employees locked both entrances to the bank Monday afternoon, posting a sign that read "closed due to an emergency." A half-dozen marked and unmarked Andover police cruisers surrounded the bank.
Unaware of the situation, numerous customers arrived and pulled on the locked door before noticing the sign.
The stand-alone bank branch is located next to a Sunoco gas station, in front of Shawsheen Plaza.
"The area lends itself" to robbery, said Hashem, noting the bank's proximity to Routes 28 and 495 and Interstate 93.
Workers at the Sunoco witnessed the suspect leave the bank, and were being questioned by police, said Hashem.
As police began their investigation Monday afternoon, officers could be seen standing in the lobby with bank employees wearing name tags. Police detectives carried tool kits into the bank that afternoon. The bank does have good security camera footage of the robbery suspect, which will be used in the investigation, said Hashem.
Andover has a second Sovereign Bank location downtown, at 71 Main St.
